This backtrace seems similar to
https://bugs.freedesktop.org/show_bug.cgi?id=12356 but this one is
against the intel driver so I'd rather be sure it's the same before
commenting there.

Could you try catching a debugging backtrace with gdb? You'll have to
install xserver-xorg-video-ati-dbg and xserver-xorg-core-dbg, log by ssh
from another machine, attach gdb to the running X with "gdb -p $(pidof
X)", reproduce the crash, and enter "bt full" in gdb. Let me know if you
need help.

thanks,
